6 Claims. .(Cl. 294-73) This invention relates to an improved containerof the type adapted to be elevated along an upright skid frame or thelike to a transporting and/or dumping position and more particularly tosuch a container, adapted for use with equipment other than transportingand dumping devices, and provided with disappearing-type lifting pins toreduce the lateral dimensions of the container.

By way of example, containers of the typeto which the invention relatesmay be used-in conjunction with transporting and dumping equipment suchas illustrated in U. S. Patent No. 2,179,779 for transporting anddumping the containers and may be used with equipment such 2,878,051 IPatented Mar. 17,

'ice

elevating equipment or like elevating normal manner and withoutditnculty.

Another object is to provide such a container having lifting pins whichcan disappear within the side walls of the container to reduce thelateral dimensions of the con tai ner or which can be raised'forcooperation with the transporting and dumping equipment or otherapparatus of the type in question.

One embodiment of the invention has been illustrated in the accompanyingdrawings, but it is to be expressly understood that said drawings arefor purposes of illustration only and are not to be construed as adefinition of the limits of the invention, reference being had to theappended claims for this purpose. 'Fig. 1 is a front elevation (i. e.,from the bail wall apparatus in the side) of an embodiment of thecontainer of the present invention showing the lifting pin pivotedwithin the side as that illustrated in U. S. PatentNo. 2,725,584 forpur- Such containers are elevated by lifting links or hooks thecontainer is guided and tilting and/or overturning thereof are preventedby skidding engagement of one of the container side walls with the skidframe. For transporting or storage purposes, the skid frame is thenmoved forwardly on its support and the elevated container 10wered torest on the support, e. g., a vehicle chassis in the example underconsideration. For dumping purposes, a bail located at or near the topof one side wall eventually reaches and engages an elevated suspensionhook or its equivalent. Then the container can be dumped by tilting itabout the point of attachment of the bail thereto, or by allowing adrop-bottom to open.

Under normal conditions such containers can be handled as describedabove Without any difiiculty whatsoever, as attested by the widespreaduse of this type of equipment. In some cases, however, as in the use ofthe container with apparatus as disclosed in Patent No. 2,725,584,referred to above, it is desirable and necessary for the lateraldimensions of the container to be held to close tolerances so that thecontainer may be used with equipment requiring a close or secure fittherewith. Under these circumstances permanent extension of the liftingpins from the side walls of the container is undesirable since thelifting pins will engage with other parts of the apparatus and interferewith the proper use of the container while at the same time requiring anexcessively large aperture in the apparatus to receive the container.Reduction of the over-all width of the container by providing liftingpins which will disappear into the side walls of the container istherefore necessary for a proper handling of the container in the usingapparatus, as will be explained in greater detail hereinafter, and anobject of the present invention is to provide an improved container ofreduced over-all width for use under such special conditions which canalso be handled by transporting and walls of the container and rotatedinto position for en'- gagement by the lifting links or the like;

Fig. 2 is a side view of the embodiment of Fig. 1 as seen from the righttherein showing a lifting pin in raised position for engagement by thelifting links or the like and further showing a construction for theaperture in the side wall of the container into which the lifting pinrotates when not in use;

Fig. 3 is a view partly in section on the line 3-3 of Fig. 4 and showinga construction for the aperture in the side wall of the container forreceiving the lifting pin'when not in use and the construction of thepivot of the lifting P a Fig. 4 is a view from and Fig. 5 is a partialinterior view of a side wall of the container of Fig. 1 showing aconstruction for the aperture receiving the lifting pin, the arrangementof baflle plates to prevent lodging of material behind the walls of theaperture and the arrangement of the guide strip with respect thereto.

Referring now more particularly to Figs. 1 and 2, the container thereshownis of the well known drop-bottom type. The container is elevated onthe transporting and dumpingequipment by means of lifting pins 10 and11, each such pin being located approximately centrally in itsrespective end wall of the closed container. As will-be understood bythose familiar with this art, drop-bottom 12 is provided with triangularwings 13 and 14 at each end thereof and the lifting pins 10 and 11 arelocated near the apices of these wings so that as the lifting links orthe like elevate the container, they also hold the dropbottom 12 inclosed position.

In the form of container chosen for illustration ofthe invention, aspecial shape is employed in which the right-hand upper corner of thecontainer '(as seen in Fig.2) is removed, leaving a beveled or inclinedwall 15 and'the left-hand upper corner of the container is also removed,leaving a similar beveled or inclined wall 16, this'shape being ofadvantage when such containers are employed with apparatus, such asstreet sweepers, as disclosed in Patent No. 2,725,584. A bail 17 islocated at the top of the bail wall 18, projecting upwardly therefrom tosubstantially the same level as the top edge 19 of the container. Bail17 is pivoted at 20 and is received in a suitable recess 21 formed ininclined wall 16 so that bail 17 may be moved to a position in therecess where it will not interfere with use of the container inapparatus such as the street sweeper referred to above. Thisarrangement, for rotating and telescoping the bail is disclosed andclaimed in U. S. Patent No. 2,758,733. f When the container of thepresent invention is to be used with sweeping apparatus, such asidentified above, the triangular wings 13 and 14 are provided at theirapices with fixed projecting pins 22'and 23 which are engaged the rightof the detail of Fig. 3;

bythe lifting devices of the sweeper apparatus to elevate the containerinto its position in the apparatus and to hold bottom 12 of thecontainer in closed position while the container is in the sweepingapparatus.

Guide strips arepreferably provided for the edges of triangular wings 13and 14 and, as shown in Fig. 2, one such guide strip 24 is mountedexternally to overlap the right-hand edge of wing 13 and the adjacentedge of the side wall 25 of the container, being suitably secured as bywelding to one of these parts, for example, the side wall 25. A similarguide strip 26 is mounted to overlap the inside of the left edge of wing13 and the adjacent edge of said wall 25 and is suitably secured as bywelding to one of these parts, for example, the side wall 25.

The construction of lifting pins and 11 and of the apertures forreceiving these lifting pins in lowered position are identical and itwill therefore be necessary to describe this structure only with respectto one such lifting pin and, for purposes of illustration, thisstructure will be described with respect to lifting pin 10. As best seenin Figs. 2-5, wing 13 is rectangularly cut away at 27 to form arectangularly shaped aperture therein. Aperture 27 is boxed ininteriorly of the container by a side wall 28, a rear wall 29, a secondside wall 30 and a top 31, these several elements being suitably joined,as by welding, to each other, to the bottom 12 of the container and tothe edges of aperture 27. The upper edge 32 of aperture 27 may besuitably reinforced interiorly by a reinforcing strip 33 which issuitably secured thereto as by welding and is also secured to theadjacent portions of side walls 28 and 30 and top 31. A bafile plate 34extends from the joining edges of back 29 and side wall 30 extendsangularly and rearwardly therefrom to engage wing 13 at 35, baffle 34being suitably secured to adjacent elements as by welding. A top 36extends from baifie 34 to wing 13 and to the adjacent edge of top 31 andis suitably secured to these elements as by welding. Baflle 34 and top36 are provided so that material to be dumped will not lodge betweenside wall 30 and wing 13.

A horizontal cylindrical pin 37 extends between side walls 28 and 30 andis spaced from rear wall 29. Reinforcement around pin 37 at side walls28 and 30 may be provided by hearing blocks 38 and 39 suitably securedto their respective side walls.

Lifting pin 10 is mounted for rotation on pin 37 and extends downwardlywithin the box-type enclosure surrounding aperture 27 when not in use.Pin 10 extends laterally outward from wing 13 in raised position and inengagement with edge 32 of aperture 27 and reinforcing block 33 forengagement by the lifting links or the like. Lifting pin 10 is seen tocomprise side pieces which are mounted on the ends of a sleeve 40 as bymeans of welded connections 41, the sleeve being rotatable on the pin37. The side pieces are provided with inturned portions 42 and 43 andwith outer parallel portions 44 and 45. A cylindrical pin 46 is suitablysecured between parallel portions 44 and 45, as by welding, andterminates in a cap 47. A reinforcing plate 48 is secured to the innerend 49 of pin 46 and is mounted on sleeve 40 in a manner similar to theside pieces. The side pieces and the plate 48 are tied together by a topplate 50 and if desired by one or more bottom tie plates 51. The sidepieces are provided with suitable shoulders 52 to engage rear Wall 29when pin 10 is in lowered position to hold the end of pin 10 and the cap47 away from rear wall 29 for easy manual engagement.

With this construction of the lifting pins 10 and 11 it is now readilyapparent that when the lifting pins are not in use they will rotateunder the action of gravity into position within the container adjacentthe apertures in wings '13 and 14, respectively. When in this loweredposition the lifting pins do not extend beyond wings 13 and 14 so thatthe container can be handled by the 4 I t lifting pins with elements ofsuch sweeper apparatus. 0n the other hand, the lowered pins 10, 11 caneasily be swung by hand into their outwardly extending positions forengagement by the lifting links or the like of the transporting anddumping equipment. To insure that the pins remain in this position andare not accidentally dislodged therefrom during handling of thecontainer, it may be desired to provide suitable retaining means. Asshown, an eyelet 53 is suitably secured as by welding to the top plate50 of each lifting pin, and a short length of chain 54 is attached toeach eye and provided at its end with a ring-like member 55 adapted tofit over the pin 22 or 23 and hold the pin 10 or 11 in position. Whenthe pins 10 and 11 are lowered, the members 55 can conveniently besecured by hooking them over fingers 56 welded to the eyelets 53.

It should now be apparent that this invention satisfies the severalobjects detailed above.

It will be understood, of course, that the invention is not restrictedto the details of construction set forth in the illustrative exampledescribed above, and that various details can be made in the form andarrangement of the parts without departing from the spirit of theinvention. Accordingly reference should be had to the appended claimsfor a definition of the limits of the invention.
